Product Description

Insulation Material Customized Width Soft Moisture Proof Composited VMPET Metallized PET PE Laminate Film Heat Sealed Roll Packaging

The aluminum coating provides an extremely high water vapor barrier, effectively preventing "container rain" (condensation) from damaging goods during maritime transport or due to diurnal temperature variations. This is crucial for moisture-sensitive goods such as electronics, paper products, high-end furniture, textiles, and food.

Outer Layer: Aluminized PET Film - PET offers extremely high mechanical strength, excellent abrasion resistance, and rigidity. The aluminized layer provides superior barrier properties, effectively blocking water vapor, oxygen, and light.

Inner Layer: PE (Polyethylene) Film - Offers good flexibility, impact resistance, and excellent heat-sealing properties.

Key Advantages

Superior Moisture and Water Resistance: The aluminized layer provides an extremely high water vapor barrier, effectively preventing "container rain" (condensation) from damaging goods during sea transport or due to diurnal temperature variations.
Gas Barrier and Odor Preservation: Prevents external odors from intruding while also preventing the goods' own odors from escaping, maintaining quality and original flavor.
Rust and Corrosion Prevention: Forms a physical barrier, completely separating goods from the container's metal interior.
Enhanced Strength and Abrasion Resistance: The PET layer provides strong protection, allowing the liner to withstand friction and impacts from pallets and containers.
Cleanliness and Hygiene: The smooth, flat surface does not easily accumulate dust, making it easy to clean and disinfect.
Light Reflection and Heat Insulation: The glossy aluminum surface reflects some light and radiant heat, helping to maintain a relatively low temperature inside the container.

Applications

Inside containers, this material typically appears in two forms:

Container Lining: A PET aluminized composite PE film is pre-laminated onto honeycomb panels, corrugated sheets, or other lightweight, high-strength materials to create standard-sized "linings," which are then directly installed on the container's inner walls.
On-site Adhesive Film: A roll of PET aluminized composite PE film is directly adhered to the cleaned container's inner walls, offering greater flexibility.
